Performance testing new Leddar technology to assess operational stability and accuracy under remote extreme outdoor environmental conditions

Leddar是一种新的、获得专利的低成本、重量轻、功耗低的测距技术， 由魁北克的Leddartech开发的飞行时间原理。该技术具有广阔的应用前景， 随着当前客户端应用程序的开发，从高速公路交通监控到生产线 质量控制到目前为止，远程户外环境监测是一个未经测试和未经证实的应用领域 存在巨大潜力的地方。然而，在这种应用开发成为可能之前，稳定性， 基线技术在一系列极端和受控环境下的准确性和可靠性 必须评估条件。迫切需要这些数据来协助新的传感器设计，以及 为潜在客户和开发者验证技术。莱斯布里奇大学位于 由于我们在激光雷达方面的内部专业知识， 测距），数据记录器编程，并由于在滑雪山上经营一个高山研究研究基地， 并设立了自动气象站，监察一系列的环境情况。 拟议项目预计将于2015年8月至2016年1月实施。具体研究 目标包括：1）设计和构建控制和数据记录接口; 2）设计和构建冬化 3）与环境传感器同时安装，以测试在一定范围内的雷达性能。 条件; 4）关于leddar模块性能的报告。测试将在三个自动气象条件下进行 城堡滑雪山上的站，跨越1400至2500 masl的海拔范围，并遇到 冬季气温可达零下40摄氏度，风速超过100节。Leddar测距精度和 将在所有条件下连续监测数据收集稳定性。对于每个安装位置， Leddar传感器将与现有的持续监测温度的仪器放在一起， 降水量、积雪深度、入射短波辐射、净辐射和风速。

Leddar is a new, patented low-cost light-weight low-power-consumption ranging technology based on optical time-of-flight principles developed by Leddartech in Quebec. The technology has broad application potential, with current client application developments ranging from highway traffic monitoring to production-line quality control. As yet, remote outdoor environmental monitoring is an untested and unproven application area where significant potential exists. However, before such application development is possible, the stability, accuracy and reliability of the baseline technology under a range of extreme and controlled environmental conditions must be evaluated. Such data is desperately needed to assist with new sensor design, as well as validation of the technology for potential clients and devlopers. The University of Lethbridge is well positioned to support this product design and validation due to our in-house expertise with lidar (light detection and ranging), data logger programming and due to operating an alpine research study site on a ski hill where automatic weather stations have been set up to monitor a range of environmental conditions. The proposed project is expected to be carried out from August 2015 to January 2016. Specific research objectives include: 1) Design and build a control and data logging interface; 2) Design and build a winterized power supply; 3)Install concurrently with environmental sensors to test leddar performance under a range of conditions; 4)Report on leddar module performance. Testing to be conducted at three automatic weather stations on the Castle ski Hill, spanning an elevation range of 1400 to 2500 masl and encountering temperatures down to -40 deg C and wind speeds exceeding 100 knts during winter. Leddar range accuracy and data collection stability will be monitored continuously during all conditions. For each installation location, the Leddar sensors will be co-located with existing instruments that are continuously monitoring temperature, precipitation, snow depth, incoming shortwave radiation, net radiation and wind speed.
